In this paper we describe the calculus TCCS, an extension of the process algebra CCS with temporal constructs. The calculus is useful for the formal analysis of the timing aspects...
Traditionally, the various semantics of the process algebra Csp are formulated in denotational style. For many Csp models, e.g., the traces model, equivalent semantics have been gi...
Abstract. We discuss, compare and relate some old and some new models for incomplete and probabilistic databases. We characterize the expressive power of c-tables over infinite dom...
Current research on qualitative spatial representation and reasoning usually focuses on one single aspect of space. However, in real world applications, several aspects are often ...
Abstract. Motivated by research on how topology may be a helpful foundation for building information modeling (BIM), a relational database version of the notions of chain complex a...
